Why preventive care is important

Remember the old saying that "an ounce of prevention is worth a pound of cure"? This can be especially true when it comes to preventive health care. Maintaining or improving your health is important - and a focus on regular preventive care, along with following the advice of your doctor, can help you stay healthy.

Transitional cell cancer of the renal pelvis or ureter

Jan 19, 2005 Viewed: 299

Alternative names
Cancer - renal pelvis or ureter

Definition
Cancer of the renal pelvis or ureter involves the growth of cancerous cells in the collection system of the kidney. This includes the part of the kidney (the pelvis and its subdivisions or calyces) that empties urine into the ureter, which leads to the bladder.

Causes, incidence, and risk factors

As a group, renal pelvis and ureter carcinomas are uncommon and account for no more than 5% of all cancers of the kidney and upper genitourinary tract. They affect men more commonly than women and are more common in people older than 65.

Tumors of the renal pelvis and ureter are usually transitional cell cancers. Approximately 10% are squamous cell carcinomas.

The causes of this cancer are not completely known. Chronic irritation of the kidney from harmful substances excreted in the urine may be a factor and may result from the following:

Smoking

Analgesic nephropathy

Exposure to aniline dyes and chemicals used in the manufacturing of leather goods, textiles, plastics, and rubber

Patients with a previous history of bladder cancer are also at risk.

Symptoms

Back pain, located where ribs and spine meet

Bloody urine

Burning, pain, or discomfort with urination

Dark, rust-colored, or brown urine

Fatigue

Flank pain

Need to urinate frequently at night

Unintentional weight loss

Urinary frequency or urgency

Urinary hesitancy

Signs and tests
Examination by touch (palpation) of the abdomen rarely reveals a mass or an enlarged kidney.

Blood in the urine may appear.

Complete blood count (CBC) may show anemia.

Cancer cells may appear on the following tests:

Urine cytology (microscopic examination of cells) obtained during a cystoscopy

Urine cytology obtained from a urine sample

The tumor, or signs of urinary obstruction, may appear on:

Intravenous pyelogram (IVP)

Kidney ultrasound

Abdominal CT scan

MRI of abdomen

Renal scan

An x-ray, CT scan, or MRI of other areas of the body may show metastasis of cancer from the kidneys.

Treatment

The goal of treatment is to eliminate the cancer.

Surgical removal of all or part of the kidney (nephrectomy) is usually recommended. This may include removal of part of the bladder and surrounding tissues or lymph nodes. If the tumor is in the ureter, it may be possible to remove it while preserving the kidney.

When the cancer has spread outside of the kidney or ureter, chemotherapy is often used. Because these tumors behave similarly to transitional cell carcinoma of the bladder, the chemotherapy regimens used are similar to those used for bladder cancer.

Support Groups
The stress of illness may be eased by joining a support group whose members share common experiences and problems. See cancer - support group.

Expectations (prognosis)

The outcome varies depending on the exact location of the tumor and whether the cancer has metastasized. Cancer localized to the kidney or ureter can be cured with surgery.

Cancer that has metastasized to other organs is usually not curable, though there are exceptions.
